The object of this invention is :to provide an ensilage carrier including af'body adapted to be receivedfby the frame of an elevating device-movable .vertically along the wal'lyof a silo, the body `being detachable from the frame for mounting on atruclrbyineans of which thematerial is carried tothe feeding trough. Y

Y A further object is -to provide la lparticular l form of counterfba-lan'ced frame,witlibra1king lmeans therefor, and a body having -a hinged `end wallfconstitutinga closuref'forthe body `when the latter isinounte'd-fon theetrucl, and

Vforming a platform for the operator when l said body is in Vverticalposition on the ele- .vater frame.

YVith .the foregoing and other objects 'in view, `theinventionconsists in the novel construction :and arrangement of elements de- 30 scribed,illustratedand claiin'e'cbit Vbeing understood that modifications 4may be imade Within v,the scope of the l'claiin without-de parting from the spirit of the invention.

A In the drawings forming part of this ap- 2 plication:

Figure 1 is a view in elevation showing a silo witha vertical track on one side thereof, and showing the counter balanced frame mounting a detachable body or receptacle for the ensilage.

Figure 2V is a view in elevation showing the frame, from one side thereof, and showing the body in the frame and also in side elevation.

Figure 3 is a detail view, taken on line 3 3 of Figure 1, and constituting a section thru the body and the track structure, with a portion of the wall of a silo.

Figure 4 shows the frame in rear elevation, and illustrates especiallyl the construction and operation of the braking devices.

Figure 5 is a detail in section showing elements referred to below.

Figure 6 is a plan view of the body, one l end portion, constituting a swinging closure being illustrated in dotted lines as in open position. e

Figure 7l is a section on line 7-7 of Figure l, showing the mounting of the track 59 structure and showing elements of the ladder.

The wall ofthe silo is designated 10, and carriedth-ereby are-railsll and lQretained yin position by bracket'svor .other suitable -securing .devices 13, shown in thiscase asf-,being .in the Iforin of transverse bars .with outward- .turned ends.

One .end portion .of the body, constituting a permanentend .thereof 1isJde-signated :21,.and the .otheren'dA 22 forms a closure or door, .mo-u ted .at ..23 for swinging movement and facilitating the :loading and iunloa'ding. operation,` said ido'or 'also constitutfing Aa .platform vfor :the `operator y.when the :body .lis p'ositionedon the .carrier as in Fig-'- :ure 1,1t'he' fra-ine 2O constituting. the `prin :cipalfelement ofit'hecarrzielr. 1

' This frame QOinay .include a lower :outwardly deflected portionadapted for engagement'byvanangle fbar 24 on end. member "21. The body isreadily detachable from the rectangular .inclosing 'and hoisting iframe or carrier 20, because in Figure ..2 the onlyen- :ga/gement :at'the bottom i-sat 20,`24, and at 'the top for elsewhere .any `.well 4known securling devices -such as hooks (one 'of ywhich is shown '.conv-entionally'.) may Ibe employed. i

Carried .by 4the :frame .is a vertical guide and brake rail :ffmounted in .affixed position .as at-27,:and a. rail 28 is inovfably mounted 'by `means :of pin and slot connection shown at 29, the rail last named being movable on transverse bars and 3l of the frame. Brackets such as 32 are secured in any suitable manner and bars 33, passed loosely thru apertured portions of these brackets, are encircled by springs 34.

The bars 33 are secured at 35 to the guide rail 28, and the springs exert outward pressure under normal conditions, so that the brake rail and guide rail 28 is normally in condition to act as a brake as the frame operates vertically along the rails ll and l2. A suitable brake lining is shown conventionally at 39.

In order to operate the movable brake rail 28 and release the latter from its normal contact with the adjacent stationary track rail, I provide a plurality of levers one of which is designated and is pivotally connected with element 26 at the point 4l, and is further connected by means ofa pin or bolt 42 with a lug 43 on lever 44. This element last named is pivoted at 45 to movable brake member 28 and the upward movement of the right hand end of lever 44 in Figure 4, by

means of the operating rod 46, produces the release movement of the brake element 28. It will be observed that the handle member' 47 connected with rod 46 is in such position that it will be easily accessible to the opera- .tor when standing on platform 22 of the body or receptacle, which element 22 constitutes a closure when the receptacle is being used as a truck, as for instance in Figure 8.

In order to supply convenient means for transporting the material from the silo to the feeding trough, I employ the receptacle previously used in removing the material from the silo, and mount this receptacle or body on a frame constituting a truck frame, or merely a truck, this device being mounted ron a plurality of wheels such as those shown at 50, 5l, 52, the wheels being of the caster variety and carried by elements or bolsters l5 54 and 55 which in turn form a part of the truck structure.

This structure includes side elements 56 and 57. However, any suitable truck may be employed, butin order that the body may be properly retained it is desirable to mount the body on the truck in the manner shown in Figure 10 in which I have illustrated a plurality of invertedchannel elements 60 and 61 connected with the rear bolster by means of bolts or the like 62 and spaced to receive therebetween one flange of an angle element 63 carried by the body.

The structure of Figure 2 is raised from the position of Figure l, when empty, by the counterba-lance 17, or may beso raised, and when the container or body is loaded with material withdrawn from the silo, it will descend because heavier than the weight. Control is secured by the brake mechanism of Figure 4, a movable rail at the left cooperating with a stationary vertical guide. The operator standing on the upper end of the body when the latter is vertically positioned, operates brake handle 47. After the body is lowered, it is released from carrier or frame vopened as in Figure 8, and forms a discharge member when tilted to lower position.

Having described the invention what is claimed is In a device of the class described, a frame, meansfor counter balancing the frame, a stationary guiding element carried by the frame, a movable guiding element carried by the frame, this guiding element constituting a rail effective along one edge thereof as a brake, resilient means bearing on the movable element and tending to force it outwardly, and a plurality of pivotally connected levers, one of which is pivotally connected with the stationary guiding element, the other lever' being pivotally connected with the movable guiding element, means for pivoting the levers together at a point between the ends of the lever connected with the movable element and operable for shifting said movable element inwardly and outwardly with reference to the stationary guiding element, while 'V' maintaining parallel relation therewith.
